Physical Science Part 1
Across
- 3. an atom or molecule with a net electric charge due to the loss or gain of one or more electrons
- 5. the force of attraction or repulsion of magnetic materials
- 7. field the region around a magnet where the magnetic force is exerted
- 9. field a region around a charged object where the object's electric force is exerted on other charged objects
- 11. pole one of the two ends of a magnet where the magnetism seems to be connected
- 16. charge more protons than electrons
- 17. force an attractive force that acts between any two objects
- 18. a form of energy caused by the movement of electrons
Down
- 1. an instrument for detecting and measuring small electric currents
- 2. a material or an object that does not easily allow heat, electricity, light, or sound to pass through it
- 4. a material that allows heat and electricity to pass through it
- 6. energy energy caused by the movement of electrons
- 8. a measure of the extra positive or negative particles that an object has
- 10. a machine that converts mechanical energy into electrical energy
- 12. field the region of space surrounding a body in which another body experiences a force of gravitational attraction
- 13. to push away
- 14. to pull towards
- 15. to send out rays; to beam or to shine
- 18. wave a wave that consists of oscillating electric and magnetic field, which radiate outward at the speed of light
- 19. a temporary magnet that loses its magnetism when the electric current is turned off
